00:20

guy at h and r block two hundred bucks to

00:21

do them for you Done and done We've already learned

00:25

how to divide one decimal by another But what about

00:28

when they're really long All we have to do is

00:31

tackle it the same way we would a really tough

00:34

looking running back head first So say we need to

00:37

divide zero point zero zero three to nine eight five

00:40

one one seven by zero point two nine one seven

00:44

five three And we accidentally jumped into the pool Was

00:47

our scientific calculator Well how do we figure this thing

00:50

out by hand Well we can start by moving the

00:53

decimal place And our divisor is many spots as we

00:56

need in order to make it a whole number in

00:58

this case if we move it One two three four

01:00

five six pots to the right We get two hundred

01:03

ninety one thousand seven Hundred fifty three Now we move

01:06

the decimal of the dividend the same number of times

01:09

we move the decimal of the divisor and we get

01:12

three thousand two hundred ninety eight point eight five one

01:14

one seven Our problem is now become three thousand two

01:18

hundred ninety eight point eight five one one seven divided

01:19

by two hundred ninety one thousand seven Fifty three still

01:22

looks like something capitals up after getting too excited but

01:26

at least we're no longer fighting by decimal From here

01:29

we do the usual long division thing Move the decimal

01:32

place directly upward and eventually we get point Oh one

01:36

one three oh seven We're definitely killing a tree or

01:39

two with his long division problems this intense but at

01:43
